[03:48:19] <awallin> alex4nde1-: hi, re trochoidal pocketing, do you have any images/videos online? were you using a voronoi-diagram/medial-axis, or something else?
[03:50:22] <Jymmm> http://www.youtube.com/watch?v=lfOrDSp-tW4
[03:56:34] <archivist> http://wondermark.com/tink8/
[04:01:28] <awallin> Jymmm: do you know how cambam does that, under the hood? can it deal with arbitrarily shaped pockets?
[04:06:15] <archivist> awallin, you could ask the cambam programmer he may tell you as he is a friendly sort
[04:07:06] <awallin> ok. last I checked the cambam stuff was on cnczone. do they hang out there still?
[04:07:18] <archivist> I met him at one of the model engineer exhibitions
[09:42:34] <kb8wmc> psha: good day to you sir
[09:49:30] <Loetmichel> *GNAH!* killed the PSU of my CNC AGAIN. Maybe te 32V 2A are NOT sufficient after all? (should have built a little bigger PSU, but the ex-Epson-LQ-PSU fits so well and i have about 100 left in the company ;-)
[09:52:14] <archivist> 2a is never enough
[10:02:58] <pcw_home> parallel 'em
[10:03:55] <pcw_home> with maybe a fractional Ohm balance resistor per PS
[10:09:33] <skunkworks_> pcw_home: did you see http://www.cnczone.com/forums/controller_computer_solutions/147097-galil_dmc-1050_controller_retrofit.html
[10:13:22] <pcw_home> Yeah I think that guy called us yesterday
[10:13:28] <tom3p> "another way to parallel SMPS's is to parallel through high current schottky diodes to isolate the supplies from each other. using schottky diodes gives only a 300mV forward drop across the diodes"
[10:13:45] <skunkworks_> pcw_home: Good? or scary?
[10:14:08] <pcw_home> But with diodes you need to add capacitors
[10:14:28] <tom3p> yeh, i used a big bulk and fed off that
[10:15:01] <pcw_home> Not scary, sounded competent
[10:15:58] <pcw_home> wanted to know if the Galil breakouts could be re-used (probably not)
[10:18:02] <pcw_home> Other people asked about the BISS capability (its there but untested as I'm too cheap to buy a BISS encoder)
[10:49:02] <skunkworks_> interesting.
[10:50:47] <skunkworks_> absolute encoder. does homing work? or does emc see it as a normal encoder?
[10:56:32] * JT-Shop homes in on a nap...
[11:03:12] <pcw_home> I dont think LinuxCNC has any absolute encoder support yet (the resolver stuff emulates a incremental encoder at the driver level)
[11:07:10] <pcw_home> Maybe there's nothing really needed for a absolute encoder (just no need to home)
[11:08:18] <pcw_home> The resolver is a special case since its only absolute for ~one turn
[11:09:01] <psha> kb8wmc: hi
[11:13:20] <kb8wmc> psha: I have the video camera working properly thanks to your help and instructions...
[11:14:01] <kb8wmc> I will try not to forget again, what I have learned from you...
[11:14:26] <JT-Shop> hi Mike, how goes the hal mystery?
[11:38:03] <mazafaka> Do I need to run 'sudo apt-get build-dep program_name' from the source directory of the program which I am trying to install?
[11:39:48] <alex4nde1-> awallin: I don't have any videos online, my stuff is all really simple though. I've mainly been writing pathes and watching how it affects the mill's load. I've got a Taig, and it's not very stiff so I'm trying to minimize shock to the tool/spindle.
[11:47:07] <psha> mazafaka: build-dep is used with name of package, not with source
[11:47:18] <mazafaka> uhu
[11:47:19] <psha> if you have source you should use dpkg-checkbuilddeps
[11:47:38] <mazafaka> from the source directory
[11:48:20] <psha> from the directory with debian/ subdir
[11:48:25] <psha> so it may find debian/control file
[11:57:22] <Loetmichel> so, back to workung aganin, ant THIS PSU will last a while (30V 6A instad of the old 32V 2A on the table below) -> http://www.cyrom.org/palbum/main.php?g2_itemId=12808
[11:57:27] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12811
[12:13:54] <kb8wmc> JT-Shop: good day sir, sorry I didn't see your message before this....how are you today?
[12:14:57] <kb8wmc> camera issues fixed and working well, have conflicts now between camera and joypad which I am attempting to resolve in the forum
[13:28:14] <mazafaka> jthornton: the wood stove: http://img-fotki.yandex.ru/get/5414/137304751.2/0_7783f_3f299963_XXL.jpg (I have bought some coal for it in pieces and as a powder).
[13:36:28] <Loetmichel> hmm, the cheap milling spindle takes shape... the material fpr the coupling is sawed off already... after that i have to make the (0,6mm aluminium sheet) Body and the electronics... and then i can donate it to the local open workshop ;-)
[13:36:36] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12814
[14:26:53] <jthornton> mazafaka: is the stick in a can of petrol for easy lighting?
[14:27:07] <Jymmm> I saw that too! lol
[14:27:47] <Jymmm> I do like the sheet of plastic near/touching the metal heat shield
[14:33:38] <Loetmichel> hmmm, hase anyone some nknowledge about axle couplings? what would one suggest to connect the motor to the spindle that is homemade-able? -> http://www.cyrom.org/palbum/main.php?g2_itemId=12814
[14:34:07] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12757
[14:34:29] <archivist> the type with rubber and a castle shape
[14:34:33] <Loetmichel> its an 8 mm chuck holder and a 5mm motor axle
[14:34:50] <Loetmichel> castle shape?
[14:34:57] <Jymmm> Loetmichel: tubing and hose clamps?
[14:35:15] <Loetmichel> Jymmm: 20-30 kRPM, 200W motor!
[14:35:24] <Loetmichel> no hose clamps ;-)
[14:35:28] <archivist> and this type http://www.arceurotrade.co.uk/Catalogue/Stepper-Motors/Oldham-Couplings
[14:35:35] <jthornton> hydraulic hose and hose clamps... I used that once to connect a lawn mower engine to a outboard lower unit
[14:35:54] <archivist> hose types are bad
[14:35:55] <Jymmm> jthornton: how did it work out?
[14:36:05] <jthornton> lasted for years
[14:36:17] <jthornton> was still working when I sold the rig
[14:36:23] <Loetmichel> hmm, oldenham seems doable
[14:36:25] <archivist> buggers slip when you dont want them too
[14:36:31] <Jymmm> Loetmichel: aluminum hex tubing and set screws
[14:36:35] <Loetmichel> i have amuminium, i have delrin...
[14:37:52] <Loetmichel> aluminium
[14:37:55] <archivist> http://img.directindustry.com/images_di/photo-m2/flexible-couplings-shaft-couplings-410984.jpg
[14:38:19] <Loetmichel> archivist: looks also doable.. and more my style ;-)
[14:38:46] <archivist> positive engagement I used bits of o ring for my first home made one
[14:38:51] <Jymmm> 1/4-20 hax standoffs and set screws
[14:38:54] <jthornton> lovejoy type
[14:38:54] <Jymmm> hex
[14:38:55] <Loetmichel> and i think i have some 6mm thick hard rubber somwhere
[14:39:47] <archivist> I had less rubber, they did wear out though, so went and bough some oldham
[14:39:47] <Jymmm> Loetmichel: this and some set screws http://images.grainger.com/B353_38/images/products/250x250/Hex-Standoff-1AJ94_AS01.JPG
[14:40:13] <archivist> Jymmm, er no
[14:40:22] <Loetmichel> Jymmm: cant do that. dont belive i got the axles PERFECT in line
[14:40:31] <Jymmm> archivist: He said home makable.
[14:40:46] <archivist> I know
[14:41:11] <archivist> and I know what machining he can do and what flexibility is needed
[14:41:11] <Loetmichel> Jymmm: where is the problem to make a oldham or the "star" type at home?
[14:41:19] <Loetmichel> i HAVE a CNC mill and a lathe ;-)
[14:41:29] <Jymmm> Loetmichel: Cool
[14:41:34] <archivist> no need to bodge
[14:42:01] <Loetmichel> archivist: bodge?
[14:42:21] <archivist> kludge
[14:42:32] <Loetmichel> ah, "pfuschen" in german ;-)
[14:42:50] <archivist> plenty examples on there i fixed it
[14:43:19] <Loetmichel> hmm, i think i give the "star" type a go
[14:43:54] <archivist> the star can have just a couple of dogs on both parts
[14:43:58] <Loetmichel> the oldham is a bit much "flying parts around" at 20krpm for me
[14:44:20] <archivist> they both are similar size
[14:45:09] <archivist> you could make http://i01.i.aliimg.com/wsphoto/v0/339609535/5mm-to-6-35mm-Flexible-Shaft-Coupler-5-6-35mm-Flex-Clamp-Shaft-Coupling-Connector-Diameter.jpg
[14:45:38] <archivist> one bit of metal and a slitting saw to make it
[14:46:06] <Loetmichel> archivist: that was my first idea
[14:46:29] <Loetmichel> but they have a spiral , havent they?
[14:46:53] <Loetmichel> dont know how to do THAT
[14:46:54] * jthornton goes back to the shop to make cannon parts
[14:47:27] <Jymmm> jthornton: 50mm balls?
[14:47:30] <archivist> Loetmichel, some are cut at 90 deg
[14:50:24] <mazafaka> jthornton: its a can of water :)
[14:53:15] <mazafaka> I plan to fit a SUV, a motorcycle, and a motorcycle with a disassembled sidecar into the garage (5.5 x 3.6 meters) soon
[14:55:14] <mazafaka> In Soviet Union, the purpose of the worker was his job. Large garages or two-or-more-story cottages were banned.
[14:56:04] <mazafaka> I will have to disassemble the soft top from the SUV to park it in the garage.
[14:56:05] <mrsun_> in Soviet Russia MIG welds you!
[14:56:31] <JT-Shop> Jymmm: 44.45mm bore
[14:57:25] <mazafaka> By the way, Jeep Wrangler is so tiny! Even compared to Land Cruiser Prado. Jeep Wrangler is only a little thicker and higher than Russian Niva.
[14:58:33] <andypugh> I wondered why it was so quiet, then realised that #emc is defunct.
[14:59:45] <mazafaka> Although, Wrangler's height either doesn't fit into the doors of my garage.
[15:01:14] <Jymmm> andypugh: That's funny, #emc forwards to here automatically.
[15:01:48] <andypugh> There are 3 people in there...
[15:03:15] <mazafaka> they're RPF (retarted perverted freaks) ??!
[15:03:52] <mazafaka> Oh this Jurassic '#EMC'
[15:06:22] <mrsun_> http://i39.tinypic.com/ddcih5.jpg <-- my wood working place is starting to take shape =)
[15:07:30] <mazafaka> I would fear of wooden structure of the building.
[15:07:37] <andypugh> Aren't you under 9m of snow then?
[15:07:52] <mazafaka> who?
[15:08:12] <andypugh> mrsun
[15:08:30] <skunkworks_> andypugh: aren't you in the middle of the ocean...
[15:08:51] <andypugh> Not yet, I just got back from Finland, I have 2 weeks at home, then leave for China.
[15:09:06] <mrsun_> mazafaka, what? :P
[15:09:14] <mrsun_> that it stands on blocks and isnt fully supported? :P
[15:09:15] <mazafaka> We have relatively not much of the snow this winter. I even have some persistent tracks of my bicycle wheels all around the town.
[15:09:42] <mrsun_> its like 20cm of snow here, and ive seen to it no snow is on that structure =)
[15:10:26] <mrsun_> going to start working on the walls as soon as i can get more stuff home for it, im out of stuffs =)
[15:10:50] <andypugh> Lack of walls would have stopped me working where we were in Finland, it was -35.
[15:10:59] <Jymmm> andypugh: try joining #emc again
[15:11:01] <mazafaka> mrsun_: no, because wood is inflammable
[15:11:32] <andypugh> Jymmm: Invite only, it ways.
[15:11:36] <andypugh> (says)
[15:11:55] <mrsun_> ahh would fear of wooden structure =)
[15:12:00] <mrsun_> not fear for the wooden structure :P
[15:12:07] <Jymmm> andypugh: can you exit #linuxcnc then try join #emc?
[15:12:19] <andypugh> And miss all this witty banter?
[15:12:46] <andypugh> Ah, OK, that seems to work.
[15:12:51] <Jymmm> ok cool
[15:13:21] <mazafaka> I more and more often think of concrete walls and maybe half a meter of the clay from the inside.
[15:14:22] <andypugh> They seem to like wooden buildings in the US, though it seems unnatural to me. The way to build houses is piling rocks on top of each other to me.
[15:14:48] <mazafaka> Not the flame itself but essentially toxic materials can be dangerous in what can be called a survival situation
[15:16:10] <mrsun_> im from sweden, almost everything here is made in wood =)
[15:16:19] <WalterN> Jymmm: I was...
[15:16:52] <Jymmm> WalterN: Ok, cool. Just cleaning up some things (you were in #emc too =)
[15:17:10] <WalterN> #emc is probably my autoconnect...
[15:17:19] <WalterN> why change the channel?
[15:17:28] <mazafaka> I'm from Russia. I own a separately standing items of real estate here and there all around the town. They are made of concrete.
[15:17:34] <Jymmm> Yeah, it SHOULD forward you to here from now on.
[15:17:50] <Jymmm> WalterN: see /topic
[15:18:42] <Jymmm> Hmmm, lets see if lawernces client reconnects
[15:19:45] <mazafaka> it makes me sad. Iused to work at a random time of the day and evening (and morning). I only can dream of something similar to the cottage, (when the garage is next to the kitchen). :)
[15:21:08] <Jymmm> By the powers of greyskull...
[15:21:36] <mazafaka> he what? has died? Jymmm... jymmm...
[15:21:50] <Jymmm> YAY!
[15:21:55] <mazafaka> we actually did love him!
[15:22:49] <mazafaka> there is he, ..>here<..
[15:26:22] <syyl_> http://dl.dropbox.com/u/24396704/2012-02-11_20-42-13_606.jpg
[15:26:24] <syyl_> done :D
[15:26:47] <syyl_> Jymmm, finaly i used a single layer of copypaper in front of a single led
[15:26:58] <mazafaka> I think americans and europeans has a gift of living separately, at cottages, when all the stuff is around them. But they take to much of the virgin areas of nature. Same bad is here, but our rich ones still prefer the flats. And usual people only own gardens which gives them greenies and vegetables for winter.
[15:27:56] <mazafaka> I have sold couple of the thingies like http://dl.dropbox.com/u/24396704/2012-02-11_20-42-13_606.jpg to become a real estate broker :)
[15:28:10] <syyl_> hehe ;)
[15:28:53] <mazafaka> (Buyers made me said 'communism is just a fake' several times before they had finally given me my money.)
[15:30:30] <mazafaka> I want to add a small winch to my motorbike, as at the one at http://icon1000.com/bike/the-roach/
[15:31:27] <syyl_> that thing looks badass :D
[15:32:14] <mazafaka> but i don't really like glamorous thingies
[15:33:13] <mazafaka> What if I use an automobile engine's starter (small electric motor revolving the engine when it runs)
[15:39:25] <mazafaka> Also, a small CNC machine which is just build around a small dish with a cake on it. Could be mind-blowing, could be sharp as a toothpaste with peppermint! (This now is a just a joke :)
[15:43:46] <mazafaka> We could decide to pull a small rig when you go off to the job each time it's Monday and it's 17th of some month. This would be twice more wise as another war! How much social noise would it produce?
[15:53:40] <Loetmichel> ok, i THINK that will be sufficient... -> http://www.cyrom.org/palbum/main.php?g2_view=core.DownloadItem&g2_itemId=12817
[15:54:20] <Loetmichel> the star will be 6mm PE sheet and the both "crowns" will be aluminium
[15:55:04] <mazafaka> Aluminum blanks you buy are of regular aluminum or it's some alloy as the one in bicycles (AL 6061 or Al 7071)?
[15:55:06] <Loetmichel> OH SH**... the crowns can only have 2 "teeth", not 4... will change drawing imediatly.
[15:59:55] <andypugh> Loetmichel: Motor mount?
[16:00:05] <Loetmichel> the coupling
[16:00:21] <andypugh> No, I mean, what is it a drawing of?
[16:00:39] <Loetmichel> cheap Spindle for a CNC mill
[16:00:55] <Loetmichel> http://www.hackerspace-ffm.de/wiki/index.php?title=Datei:Foto1519.jpg <- replacement for this
[16:01:29] <Loetmichel> which should be the moint for a proxxon FBS230
[16:01:41] <Loetmichel> but is more like a PITA
[16:02:29] <andypugh> Hmm, I would suggest a pair of angular contact bearings and a means of adjustment.
[16:02:39] <Loetmichel> the 20mm hole in the aluminium block looks like drilled with a forstner drill and a battery drill freehand, and the plexiglass mount is also rubbish
[16:03:34] <Loetmichel> thats how far i am right now: http://www.cyrom.org/palbum/main.php?g2_itemId=12814
[16:04:07] <Loetmichel> now the coupling has to be made and then the housing of the sopindle and the electronics
[16:04:18] <Jymmm> duct tape
[16:04:25] <andypugh> Have you seen the ER collets on eBay? One of those would make a nice shaft, and save you a lot of work: http://www.ebay.co.uk/itm/ER11-12MM-STRAIGHT-SHANK-COLLET-CHUCK-CNC-MILLING-LATHE-TOOL-WORKHOLDING-F82-/110813872025
[16:04:53] <Loetmichel> andypugh: the Collet is the axle if a proxxon (dremel)
[16:05:00] <andypugh> Ah, too late :;)
[16:05:05] <Loetmichel> so ther ARE already collets ;-)
[16:06:05] <andypugh> I meant "collet holder" really.
[16:06:19] <andypugh> But you are already nearly finished.
[16:06:55] <Loetmichel> i know
[16:07:47] <Loetmichel> andypugh: you mean something like this: -> http://www.cyrom.org/palbum/main.php?g2_itemId=11998
[16:07:48] <andypugh> Plexiglass for a spindle holder is an unusual choice. Can you confirm it wasn't your idea before I get very rude about it?
[16:07:51] <Loetmichel> ... alöready here
[16:07:53] <Loetmichel> already
[16:08:14] <andypugh> Yes, exactly like that :-)
[16:08:21] <Loetmichel> bu i wont donate the ER11 to a "open workspace"
[16:08:54] <Loetmichel> the CNC in question is located at "hackerspace FFM" around here where i live
[16:09:47] <Loetmichel> was there a few days ago to check it out and had pity with them, so i opted to make them a new spindle + holder
[16:11:09] <Loetmichel> all questions aswered?
[16:11:16] <Loetmichel> so no need to get rude ;-)
[16:11:23] <JT-Shop> LOL
[16:11:49] <andypugh> I guess you might choose plexiglass to add some damping.
[16:13:26] <Loetmichel> andypugh: if you want to get rude: look at my first CNC mill... about 15 years or so ago... -> http://www.cyrom.org/palbum/main.php?g2_itemId=2859
[16:13:37] <Loetmichel> ... and still: it has done some work ;-)
[16:14:20] <Loetmichel> that "machine" is made ENTIRELY of Plexiglass ;-)
[16:14:33] <mazafaka> http://www.cyrom.org/palbum/main.php?g2_itemId=2859 <-- but the spindle is weak for milling and engraving (as you had told recently)?
[16:14:51] <Loetmichel> it is
[16:14:58] <mazafaka> (when we talked of mini drills)
[16:15:04] <Loetmichel> that was my first attempt in CNCing ;-)
[16:15:14] <Loetmichel> about 15 jears ago
[16:16:31] <Loetmichel> the 5mm stainless steel Theads as drives had gnawed away the brass nuts in under 8 operating hours, even the lightest milling caused som flexing in the gantry, the steppers are out of old 5,25" floppy drives....
[16:16:55] <Loetmichel> and the spindle had about 20 mil play in the bearings
[16:17:07] <Loetmichel> but it worked more or less ;-)
[16:18:16] <Loetmichel> but now back to work, have to make some "star" couplings for the new spindle ;-)
[16:23:09] <andypugh> Loetmichel: The old one reminds me of Orac. Not the Denford lathe, the computer: http://en.wikipedia.org/wiki/Orac_(Blake%27s_7)
[16:23:45] <Loetmichel> hrhr
[17:19:27] <clytle374> I've got a problem with the Mycenter-4 project. I'm starting to think I'm going to leave it gear drive with the high low clutches
[17:19:50] <clytle374> Is there a problem if I got that route and add an encoder to the spindle?
[17:20:29] <clytle374> Can you set 2 different pids for the high and low gears?
[17:20:39] <clytle374> Or am I over thinking it?
[17:42:10] <JT-Shop> clytle374: spindle motor is a servo?
[17:49:58] <andypugh> clytle374: You might find that 1 PID can handle both gears.
[17:51:20] <andypugh> Maybe set the FF1 to suit the high gear, and let the I-term ramp the motor speed up in low gear.
[17:51:37] <andypugh> (I am assuming a spindle-mounted encoder)
[17:52:05] <JT-Shop> andypugh: when is the departure to the far east?
[17:52:10] <andypugh> If it is a motor-mounted encoder then you could look at the "gearchange" HAL component.
[17:52:18] <andypugh> JT-Shop: A week on friday
[17:52:34] <JT-Shop> neat!
[17:53:45] <JT-Shop> is there a url to track the vessel?
[17:55:23] <andypugh> www.clipperroundtheworld.com -> race viewer
[17:55:54] <JT-Shop> thanks
[17:56:11] <andypugh> I will be on the good ship Derry-Londonderry
[17:56:48] <JT-Shop> leg 6?
[17:56:59] <andypugh> Yes
[18:02:16] <JT-Shop> I will be following your progress from swamp east Missouri...
[18:02:39] <clytle374> Sorry, had to step away
[18:02:55] <clytle374> Thanks, just wanted to be sure there wasn't a gotcha
[18:05:13] <clytle374> I was going to belt drive it but looking at it I'll have to cut a large amount of webbing away
[18:06:11] <JT-Shop> interesting path the lead vessel has taken
[18:06:41] <JT-Shop> very long tacks
[18:06:45] <clytle374> I'll watch the race from dry land *landlover
[18:07:11] <JT-Shop> I used to live on a small sailing vessel in the Gulf of Mexio
[18:07:25] <JT-Shop> Mexico
[18:17:25] <Jymmm> JT-Shop: And you are now land/swamp locked why?
[18:19:42] <andypugh> Taking slows you down, I guess, so you might as well only tack when you are heading into light wind, or land.
[18:20:06] <JT-Shop> well I started out on the Aleutian Islands ended up on the gulf coast and settled on the middle you know
[18:20:28] <Jymmm> JT-Shop: But, you stepped on land, why?
[18:20:45] <andypugh> I might be heading close to the Aleutians. The Great Circle route would be to the North of them.
[18:21:14] <JT-Shop> gets a wee bit chilly up there this time of year
[18:22:25] <andypugh> Yes, I will be packing thick socks.
[18:22:25] <Jymmm> JT-Shop: Couldn't you have sailed to the warmer parts of the world?
[18:24:03] <JT-Shop> I was sailing in the warm part of the world
[18:24:04] <Jymmm> andypugh: and those socks are electric?
[18:24:18] <JT-Shop> I was born on King Salmon
[18:24:47] <andypugh> The crews were having a hard time in the heat last week. I prefer cold, at least you can put more clothes on.
[18:25:22] <Jymmm> JT-Shop: You be a nanook of the north?!
[18:26:16] <Jymmm> JT-Shop: Ever sneak over to Russia?
[18:27:25] <JT-Shop> not allowed when I lived there LOL
[18:27:42] <Jymmm> bummer
[18:27:49] <JT-Shop> yea Andy you can always adjust to the cold easier than the heat
[18:28:26] <JT-Shop> old Russian Orthodox grave sites to visit when I was a kid
[18:29:07] <JT-Shop> Jymmm: actually I'm from English stock with a bit of Irish tossed in for flavor
[18:29:41] <Jymmm> JT-Shop: Well, sorry about the English part.

[18:34:10] <Jymmm> other == chicken, sausag,e etc
[18:37:08] <Jymmm> Can anyone think of any "stick" (not sheet) material that can be cut to length that does NOT need finishing (sand, paint, stain, etc) work?
[18:38:11] <Jymmm> preference to black
[18:41:34] <syyl_> cold drawn steel?
[18:42:09] <andypugh> Jymmm: Delrin?
[18:43:52] <clytle374> fiberglass? plastic? what's it for?
[18:44:05] <andypugh> What diameter?
[18:45:00] <andypugh> There is a whole range of Tufnol products
[18:50:40] <Jymmm> It's basically to make stands for acrylic signs.
[18:50:48] <Jymmm> some edge-lit, some not.
[18:52:05] <Jymmm> I might have to get a die made and go for extruded profile
[18:56:10] <andypugh> Ah, so, not circular in section then?
[18:56:56] <andypugh> Time to snooze.
[18:56:58] <andypugh> Night all
[19:01:25] <clytle374> JT-Shop, sorry I missed your question. It'll be motor with a vector drive, but I need an encoder for orient and taping

[21:43:34] <Jymmm> 1" thick PVC with a 7" diameter hole in it that I need to enlarge to 8". Suggestions?
[21:44:41] <archivist> use your cnc!
[21:47:00] <Jymmm> I dont have tool that will do 1" in pvc though.
[21:47:05] <Jymmm> tooling
[21:47:46] <archivist> use a smaller tool like everyone else does
[21:48:28] <Jymmm> But it won't clear 1" deep. 3/4" no problem.
[21:49:07] <archivist> get a longer endmill
[22:31:50] <Connor> Jymmm: Boring Bar ?
[22:32:22] <Tom_itx> hot melt wire :)
